How do Hypotonic, Hypertonic, and Isotonic Solutions Affect the Water Movement of a Cell?
After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

Cell Transport & Reproduction
Students are able to define the following terms: Osmosis, Isotonic Solution, Hypotonic Solution, Hypertonic Solution and Passive Transport. They read and complete a Mitosis worksheet, and play a Cell COmputer Game.

Osmosis and Dialysis
How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...
Curated OER
Blood Tonic
Students investigate the process of osmosis using fresh potato cuttings in saline solution. In this biology instructional activity, students explain the difference between hypertonic, hypotonic, and isotonic solutions. They...

Do Salt Water Fish Drink?
Students conduct an experiment with potato cores and a sucrose solution to investigate how salt water fish process water. They develop a lab report of their experiment.

Osmosis and the Cell Membrane-part 2
Students participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

Introduction to Osmosis
A chicken egg is a very large cell—perfect for investigating osmosis! Scholars conduct an experiment with vinegar and eggs that helps them understand the process of osmosis. They follow the activity with an in-depth look at osmosis...

Cells Study Questions and Definition
In this cells worksheet, students define 14 words associated with cells. They answer 12 short answer questions about the structure and function of the cellular system.

Cell Observation Exercise
Students take measurements of the distance between the objective and the slide when in focus with each objective. They determine the diameter of the field of view at each power in order to determine the size of the cells being observed.

Discovering the Structure of the Atom
Students investigate atomic and nuclear structure of matter by researching historical atomic theories. Students examine Rutherford's studies and discover that many scientific conclusions change over time as new data is collected.

Molecules Rock
Fourth graders engage in this interactive lesson which illustrates diffusion and osmosis and shows them that molecules of life move dynamically and powerfully. They must analyze their lab orally and in writing.
